hey i've got a 7510 had it for about 2 3 weeks and i love it. but i want to update and a better BB. i really want the 87xx but i dont really want to leave nextel they've been good to me. so what i'm asking is. do u guys think nextel will get a 87xx any time soon? or should i jus forget it and go with T-MOBILE? it either the 87xx or a treo?
